CI, confidence interval of the coefficient estimate; ExWAS, exposome-wide association study; ExWAS-MLR, multiple linear regression model simultaneously including all exposures selected in ExWAS after excluding redundant variables; IQR, interquartile range; NA, not applicable; NDVI, normalized difference vegetation index; N[O.sub.2], nitrogen dioxide; [PM.sup.2.5], particulate matter in the (ambient) air with an aerodynamical
diameter below 2.5 micrometers.
Based on differential flatness approach, the quadcopter dynamical constraints are checked instantaneously by computing the induced aerodynamical
roll and pitch, heading moments, and lift force, respectively.
By comparing the aerodynamical
coefficients, the blockage ratio of 0.9% is chosen, because, under this ratio, the blockage effect to the aerodynamical
coefficients reduced to the minimum while ensuring a relatively smaller dimensions of the computation domain at the same time.
As illustrated in , the aerodynamical
stability of the dynamic system is mainly determined by the sign of the net damping coefficient.
This procedure is extended to involve the complete aerodynamical
and structural behavior of blades with the nonuniform and twisted configuration .
This paper is organized as follows: firstly, the Mars entry dynamic model and measurement model based on the IMU and three orbiters are introduced; secondly, the communications brownout and blackout phenomena are predicted by an aerodynamical
tool during Mars atmospheric entry; thirdly, the information filter with intermittent measurements is derived; and lastly, the results of the navigation simulation are discussed.
Value of the coefficient k for an endlessly long link can be determined with help of aerodynamical
Boundary-layer flows over flat surfaces are fundamental for the understanding of aerodynamical
properties of the flow such as wall friction and the dynamical drag.
basis of (1) determines those impacts.
For bugs, it is aerodynamical
forces that provide this stability.
This wing had leading-edge slats which extended and retracted automatically in response to aerodynamical
forces, permitting low speeds for landing and unprecedented high speeds for flight.
